Studies of the nozzle for use of chemical spraying (I)

The mechanism of the adhesion of chemicals on the plant

Abstract

On the studies of the nozzle for use of chemicals spraying the first, discussed Colloidal chemistry and Hydraulicaly, the mechanism of the adhesion of chemicals drops on the plant or the insects. Selected its contact angle of Tensional force of drop surface for the determination factor of adhesion of chemicals drops. And observed as regared this two fundamental factor, and Wetting power, Spread power, and Penetrating power of it. And next, theoreticaly, observed for the size, shape and volume of drops. When its stick the revrse side of a leaf, we can applied the reserch of L. Lohnsteins method and Case of surface, by use of two dimensional differential calculus equation method, induced the equation of surface and its volume for the fish oil kali soap solution, by use these equation caluculated. And to its results discussed Tensional force of Adhesion, Spread Coefficient and volume. And then judged that at contact angle is 70-80°, Volume is max and its spread coefficient is -30--40.
